TWISTING-MAC'HINE FOR YARNS, COTTONS, AND THE LIKE.

Application filed November 24, 1920.

To all whom it may concern:

Be it known that I, ALLEN ARTHUR Bow- ERMAN, subject of the King ofGreat Britain, and a resident of Hope Bay, in the Province of BritishColumbia, Canada, have invented certain new and useful Improvements inTwisting-Machines for Yarns, Cottons, and the like, of which thefollowing is a specification.

My invention relates to improvements in mac iines for twisting yarn,cotton, silks and the like, or for making the same into spools, and theobject of my invention is to devise machine capable of accomplishingthis object in simple, practical, and highly satisfactory manner.

I attain this object by the construction illustrated in the accompanyingdrawings in which- Figure 1 is a side elevation of the machine.

Fig. 2 is a front end view.

Fig. 3 is a rear end view.

Fig. 4 is a detail view in perspective of the cylinder.

Fig. 5 is a detail view of the roller driving mechanism.

Similar figures of reference indicate similar parts throughout theseveral views.

1 indicates generally the front end frame of the machine consisting ofthe. side uprights 2 and 8 connected together by upper and lowertransverse members f and 5 respectively, while 6 indicates generally therear end fra .ie consisting of the side up rights 7 and 8 connectedtogether by the upper and lower transverse members 9 and 10, the uppertransverse member 9 being provided with a plurality of spaced verticalpins 11. shown in Fig. 3, on which are rotatably mounted bobbins 12filled with the material to be twisted, a guide plate 13 for the threadsbeing mounted on the frame in advance of the bobbins having separatenotches 1s for each thread to run in, as shown in Fig. 8. 15 indicates aroller mounted on the frame 1 for supporting the threads at the frontend of the machine.

Rotatably mounted between the front transverse members a and 5 is whatmay be termed the cylinder of the machine, indicated generally by thenumeral 16, consisting of upper and lower circular plates 17 and 18connected together by bars 19, 20, and 21, the upper plate beingprovided with a central tubular journal 22 extending ro- Specificationof Letters Patent.

tatably through the member 4-; While the lower plate is rotatablymounted on a shaft 23 which extends at its opposite ends through theplate 18 and lower transverse member 5, being rotatable in a bearing24!: fitted into the member 5, bevel gears 25 and 26 being secured tothe opposite ends of the shaft, as shown more particularly in Fig. 5. Asheave 27 is secured centrally to the underside of the plate 18 andthrough the sheave the shaft 23 also passes freely. I

28 indicate a shaft rotatably mounted on the cylinder 16 provided with abevel gear 29 meshing with the gear 25 and'having toward one end a spurpinion 30 meshing with a spur gear 81 secured to one end of a roller 32,this roller being .rotatably mounted on a shaft 33 one end of which issecured to the bar 19 of the cylinder.- A similar roller 34- is mountedrotatably adjacent the upper end of the cylinder on a shaft 35 alsoscoured at one end to the bar 19, as shown more particularly in Fig. 2.At suitable points on the bar 19 between the rollers 32 and 3% arms 36and 37 are pi'votally connected so as to be capable of being swungto andremaining in any adjusted position, each of which arms carries at oneend a guide roller, 38 and 39 respectively. 40 in dicatcs the maindriving shaft, operated by any suitable means, which shaft is mountedtransversely of the machine at the rear thereof and is provided with acone gear 41 belt-connected to a corresponding cone gear 42 secured tothe shaft 13 rotatably mounted on the front end of the machine, thisshaft 413 being provided with a bevel gear lt meshing with the bevelgear 26 on the shaft 23, while 45 indicates a sheave secured to shaft 10connected by a rope 46 to the sheave 2'? on the lower plate 18, as shownin Fig. 1.

The manner in which the machine operates may be briefly described asfollows. The respective threads from the bobbins are taken and carriedforwardly over the roller Patented A110". 2, 1921."

15, being then gathered together at their the guide rollers and thus thesides of the loop areprevented from flying outwardly as it is rotated.If the machine be now started in operation the cylinder will be rotatedby means of the rope 46 while the lower roller 32 will also be rotatedby the gear mechanism disposed between it and the shaft 48, ashereinbefore described, so that the threads are unwound from the bobbinsand formed into a skein by the rotation of the roller 32 and at the sametimethe twisting is effected by the rotating cylinder. It will of coursebe understood that the number of threads and the amount of twist in thefinished skein may be readily determined and controlled by therespectivespeeds at which the roller and the cylinder are driven.

From the foregoing it will be seen that I have devised a simple andinexpensive twist ing machine for yarns and the like which is hi hlypractical and efficient.

What I claim as my invention is 1. A twisting machine comp-rising aframe, a cylindrical member mounted vertically on the front end of saidframe, said member consisting of an upper circular disk having a centraltubular journal and a lower circular disk having a central aperture anda sheave on its'underside concentric with the aperture and through whichit extends, said disks being connected together by spaced vertical bars,spaced upper and lower rollers rotatably mounted on one of said bars,the lower roller being provided at one end with a gear, a suitablysupported driving shaft, a driving connection between said shaft andsaid gear, and means for supporting a plurality of filled bobbins sothat the free ends of the respective threads therefrom nay be gatheredtogether and passed through the said tubular journal and looped aroundsaid horizontal rollers.

2. A twisting machine comprising a frame, a cylindrical member mountedvertically on the front end of said frame, said member consisting of anupper circular disk having a central tubular journal and lower circulardisk having a central aperture and a sheave on its underside concentricwith the aperture and through which it extends, said disks belngconnected together by spaced vertical bars, spaced upper and lowerrollers rotatably mounted on one said bars, the lower roller bemgprovided at one end with "a gear, a rotatable shaft carried by saidcylinder having a gear at one end meshmg with the roller gear and abevel gear intermediate its length, a shaft extending vering with theaforesaid bevel gear and a bevel gear on its lower end, an intermediateshaft rotatably mounted on the frame having a gear; meshing with thelower'bevel gear of the vertical shaft, a maindriving shaft, a drivingconnection between the main shaft and intermediate shaft, a drivingconnection between the main shaft and the said sheave, and means forsupporting a plurality of filled bobbins so that the free ends of therespective threads therefrom may be gathered together and passed throughthe said tubular journal and looped around the said horizontal rollers.

3. A twisting machine comprising in combination, a plurality ofstationary spool supports, a rotatable frame having a single aperturethrough which the several strands from the spools associated with saidsup ports are adapted to be passed into the frame, a plurality ofrotatable rollers disposed to rotate about an axis at right angles tothe axis of rotation of said frame, and means for rotating said frameand oneof said rollers.

4;. A method of twisting together a plurality of strands and winding thetwisted strands into a skein, which consists in pass ing the severalstrands through a relatively small opening in a stationary member, thenforming the ends of the strands into a loop extending over a pair ofspaced rollers disposed with their longitudinal axes at right angles tothatof the opening, rotating said rollers about an axis coincident withthat of the opening and simultaneously rotating one of said rollersabout the longitudinal axes thereof.

5. A twisting machine comp rising a frame,

a cylinder rotatably supported at its ends by said frame and equipped atone of said ends with a central opening through which the strands to betwisted are introduced into the frame, a pair of spaced rotatablerollers within the cylinder extending transversely thereof, the ends ofthe said strands being adapted to be passed over the said rollers andsecured to form a single loop embracing both of the rollers,and meansfor simultaneously rotating said cylinder and one of the rollers totwist the strands together and to form the twisted strands into a skein.
